Trempealeau National Wildlife Refuge

Trempealeau National Wildlife Refuge encompasses 5,617 acres of diverse habitat
that serves as a resting and breeding ground for migratory birds and other wildlife.
Part of the Mississippi Flyway, some 251 species of birds have been observed
on the refuge's marsh, prairies, or bottomland hardwoods. While spring and fall
provide peak opportunities to observe birds, there are many species to be found
year-round.

Refuge personnel and visiting ornithologists have contributed to this bird
list. This bird list is in accordance with the Sixth American Ornithologists'
Union Checklist of North American birds as amended.

Season, abundance and nesting status for each bird's suitable habitat are coded
as follows:
* - nests on the refuge

a - abundant: common species that is very numerous
c - common: certain to be seen in suitable habitat
u - uncommon: present but not certain to be seen
o - occasional: seen only a few times during season
r - rare: seen at intervals of 2 to 5 years
